BetaFPV ELRS Micro TX Module 2.4Ghz 1W

BETAFPV Micro RF TX module is based on the ExpressLRS project, an open-source RC link for RC applications. ExpressLRS aims to achieve the best possible link performance in both speeds, latency, and range. This makes ExpressLRS one of the fastest RC links available while still offering long-range performance.

Please note, ELRS is a new open source project so please only order this if you are comfortable with regular firmware updates as the firmware is still in beta and may have some issues/bugs from time to time. We will only be able to offer limited support due to the early nature of the firmware, but we think this project has great potential.

Diagram

BETAFPV Micro RF TX module is compatible with radio transmitter which has the micro module bay (AKA JR/SLIM module bay, e.g. Frsky Taranis X9D、TBS Mambo).

Note: Please assemble the antenna before power on. Otherwise, the PA chip in the Micro TX module will be damaged permanently.

Note: Please DO NOT use 3S or above battery to power up the TX module via XT30 port. Otherwise, the power supply chip in the TX module will be damaged permanently.

Note: Please do not turn on all DIP switches at the same time. You can refer to the chart to know about DIP switches on/off based on different uses.

Basic Configuration

Firmware Warning

The ExpressLRS official project on Github does NOT support the OLED function for the moment. BETAFPV team will work with the ELRS team and make the official repository support the OLED and button function ASAP.

BETAFPV Micro TX Module ELRS V2.0.0 firmware is published. The firmware does not include the Binding Phrase. So please make sure the receiver works on officially major release V2.0.0 protocol and no Binding Phrase set.

• Support 5D buttons and the OLED menu with the official ELRS 2.0.0 release.
• The color of the LED changes automatically according to the system status.
• Other new and various features are fully synchronized with the official ELRS 2.0.0.
• When entering OLED menus page with long pressing, the connection between RF TX module and receiver works normally. Please do not change the Pkt Rate, otherwise, you must re-power the receiver.

Please refer to the official manual from BetaFPV for configuration and installation - Manual for Micro RF TX Module
